High cost of coal and natural gas could make EVs, US grid cleaner this summer

Green Car Reports

Anticipated price hikes for coal and natural gas could lead to increase use of renewable energy in electricity generation, making both the grid and EVs cleaner, according to new United States Energy Information Administration (EIA) analysis.

U-M study: When, where, how electric delivery vehicles are charged has big impact on GHGs

Green Car Congress

Now, a study from University of Michigan researchers shows that when, where and how those fleet vehicles are charged can greatly impact their potential to reduce greenhouse gas emissions. The U-M researchers found that 50% to 80% of the lifetime emissions associated with an electric delivery vehicle’s battery occur during charging.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

For battery EVs, the GHG emissions for “fuel/electricity” production are dominated by the coal and natural gas used in electricity generation. Importantly, battery EVs can be expected to operate with progressively fewer upstream emissions over their lifetimes as electricity grids “green.” Source: The ICCT. Source: The ICCT.

Electric vs. Gasoline Cars: Uncovering the Real Climate Savior

The Truth About Cars

This advantage remains true even when considering the electricity utilized for charging EVs. However, the production of electricity for EV charging can result in carbon emissions, depending on the energy source. One key distinction is that EVs produce no direct tailpipe emissions.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Reduction in annual generation cost and external emissions costs due to controlled charging compared to uncontrolled charging ($2010).

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

CMU policy briefs outline benefits and potential for adoption of electrified vehicles in the US

Green Car Congress

The first—“ Electric Vehicle Benefits and Costs in the United States ”—shows that the benefits of vehicle electrification vary based on vehicle type; driving style; climate; how supplying electricity is generated; and time of charge. Further, drivers should not be encouraged to charge at night in coal-heavy regions.
